Jelly Bean, which includes Android 4.1 and 4.2, is now installed on 33 percent of all devices. Of that split, 4.1 makes up 29 percent and 4.2 is bringing up the rear with 4 percent of the installations. Of course, 4.2 is only offered on a small number of phones and tablets, so the lower install base makes sense.Gingerbread still sits atop the throne, holding 36.5 percent between all its different variations. That figure remains high because many budget devices come with this version installed, but the rise in Jelly Bean indicates that users are moving towards higher-end models.

Ice Cream Sandwich is installed on 25.6 percent of devices, a two percent drop compared to last month. Other versions including Froyo, Eclair and Donut only account for 4.8 percent of the total Android user-base.

With Android 4.1 and 4.2 growing almost 5 percent month to month, it's highly likely that we'll see move past Gingerbread in the next month or two and become the most used version of the mobile OS. That is, of course, if it's able to keep its current rate of growth.
